After hearing that his family had gone underground looking for him, Kili felt awful--especially once he saw people fresh from down there. What had Thorin and Fili seen? Were they okay?

Needless to say, he went home to wait for him--and of course they'd get back after he stepped out to go buy dinner from one of the food stalls nearby. He goes up to his room to wait, stopping when he sees Fili.

"I'm a dumbass."
